QADC64E Legacy Mode Operation
operations have no effect. Each location in the CCW table corresponds to a location in the result word
table. When a conversion is completed for a CCW entry, the 10-bit result is written in the corresponding
result word entry. The QADC64E provides 64 CCW table entries.
The beginning of queue 1 is the first location in the CCW table. The first location of queue 2 is specified
by the beginning of queue 2 pointer (BQ2) in QACR2. To dedicate the entire CCW table to queue 1, queue
2 is programmed to be in the disabled mode, and BQ2 is programmed to 64 or greater. To dedicate the
entire CCW table to queue 2, queue 1 is programmed to be in the disabled mode, and BQ2 is specified as
the first location in the CCW
To prepare the QADC64E for a scan sequence, the software writes to the CCW table to specify the desired
channel conversions. The software also establishes the criteria for initiating the queue execution by
programming the queue operating mode. The queue operating mode determines what type of trigger event
causes queue execution to begin. A “trigger event” is used to refer to any of the ways to cause the
QADC64E to begin executing the CCWs in a queue or sub-queue. An “external trigger” is only one of the
possible “trigger events.”
